AUGUSTINE J. POCOCK, OF DAYTON, OHIO.

NOZZLE-VALVE.

Application filed. December 4, 1915.

To all whom it may concern:

Be it known that I, AUGUSTINE J. P0- ooox, a citizen of the UnitedStates, res1ding at Dayton, in the county of Montgomery and State ofOhio, have invented certain new and useful Improvements inNozzle-Valves; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

This invention relates to improvements in valves and more particularlyto an improved nozzle valve for filling the gasolene tanks ofautomobiles. In filling such tanks F. there is liability of overflowingbecause of the inability of the person operating the pump to know justexactly the amount of oil that is being delivered thereto.

The object of the present invention is to provide a nozzle valve havingstructural features as hereinafter described and claimed whereby aquick, positive and reliable manipulation of the valve is obtainable.

The invention will be more fully described in detail in connection withthe accompanying drawings.

Referring briefly to the accompanying drawings, Figure 1 is an elevationof my improved nozzle valve; Fig. 2 is a section thereof on the line a-aof Fig. 1; Fig. 3 is an elevation of the stuffing box and valveoperatingparts removed from the nozzle.

In a detail description of the device, similar reference charactersindicate the same parts in the several illustrations.

The receiving branch 1 and the discharge branch 2 constitute the casingor body of the nozzle, the former being provided with internalscrew-threads for connection with the flexible pipe leading from thesource of supply. The discharge branch 2 has a suitable number ofsurface projections 3 for the convenient attachment of a reducer ordischarge spout i which is adapted for insertion into the inlet openingof the tank to be filled. At the entrance to the discharge branch of thenozzle, a puppet valve 5 is located and cooperates with a seat 6, saidvalve having extensions or wings 7 which at all times lie within theentrance to said discharge branch and serve to guide the Specificationof Letters Patent.

Astem 8 is united to said valve and extends through a stuffmg box 9provided in a cap 10. The cap 20 has an exteriorly screw-threadedextension 11 which unites the cap with an openlng above the valve and anannular flange 12 engages a packing gland 13 and the union between thecap and the upper branch of the nozzle is effectually sealed. The top ofthe cap 10 is provided with two oppositely positioned lugs or offsets14;, portions of the upper ends of which are tapered as at 15 and otherportions are straight as at 16. The stufling box cap 10 issurmounted bya cupshaped member 17 having an annular knurled surface 18 which thefingers grip in turning said member. The said cupshaped member 17 ispinned to the upper end of the valve stem 8 and forms the upper closureof the stuffing box. The lower end of the member 17 has oppositelydisposed cam surfaces 19 and 20 which co-act with the lugs or offsets 14in opening the valve and maintaining it open. The deepest part of eachof said cam surfaces terminates in a straight surface 21 and a stop 22.In turning the stem and the valve therewith from the closed position ofthe valve, the cam surfaces 19 and 20 ride on the tapered surfaces 15 ofthe lugs 14, and the continued movement of the member 17 causes thestraight surfaces 21 to ride onto the straight surfaces 16 of said lugswhich is the limit of the movement of said member 17 in that directionowing to the stops 22. At this time the valve is maintained open. Inorder to permit the spring 23 to close said valve, a very slightmovement of the member 17 will bring the straight surfaces 16 and 21 outof contact and the valve will be instantly closed by the spring, theextent of said movement being equal to the length of the straightsurface 16 which it will be observed is small.

Having described my invention, I claim.

In a valve of the character specified, a member forming a liquiddischarge passage, a valve controlling said passage, a stem extendingfrom said valve, a screw-cap mounted upon said member and having anupwardly extended portion forming a stuifing gland for'the valve stem,said screw-cap having lugs extending laterally from opposite sides ofthe stuffing gland portion of said cap, the upper ends of said lugshaving cam and straight surfaces, an upper cap mounted above saidscrew-cap to which the valve stem is connected, said upper cap havingoppositely disposed cam surfaces Which terminate in straight surfacesand downwardly extending stop surfaces at the terminals of said straightsurfaces, the said 0ppositely disposed cam surfaces cooperating with thecam surfaces of the lugs of the screw-cap in opening the valve and the 0straight surfaces cooperating With the AUGUSTINE J.
